Abstract
A driver circuit for driving a power transistor includes a converter having a first transistor and a second transistor coupled in series between a supply node and a reference node. The converter is configured to receive a first signal and in response thereto generate a second signal for selectively controlling status of the power transistor. The ratio of a first leakage current of the first transistor to a second leakage current of the second transistor is used in the generation of the second signal which is applied to the control terminal of a transistor switch that is selectively actuated to turn off the power transistor.
